To all 'whom 'it may concern:

'Be itknown .that I, 'SAMUEL H. STEIN, ay citizen of the United States, residing at Los Angeles, in the'` county of-Los Angeles and State of California, have invented new and useful Improvements -in 'Loose-Leaf Binders, of which the following is a specification.A

\ This invention relates to improvements in g loose leaf binders, and it is the object of the invention .to provide aY binder for loose leaves of any kind-inwhich the leaf engaging means may be adjusted to various points l with respect to each other to bring them opposite perforations or apertures formed in the sheetsto be' secured. v

n It. is 'also an object of the invention to provide a binder with a securing back portion .having openings formed therein and leaf engagmg securing means adjustably mounted in .said openlngs. y s v It is a further object of the invention to provide a loose-leaf binder in which the back of the binder is formed with openings, the

L. 1 back also having guideways formed therein y and to provide -sliding means engaging said back and moving in said openings, the said Y- sliding means having openingfand closing fasteners for securing loose 'leaves to be bound.

In the accompanying drawing forming a part ofthis specication, Figure. 1 is a perspective vieivof a portion of the improved loose leaf binder,l the cover leavesthereof being open to reveal the back and leaf secur- ,35 ing means. ig. 2' is an enlarged detail section View taken transversely through the i back ofthe binder and one of the leaf securingmeans, the leaf engaging arms thereof being shown in elevation tahen'on the line .140 2-2 of Fig. 1. Fig. 3 is a similar sectional view but showing the leaf engaging port-ion r in open position. Fig. 4 is a longitudinal `sectional view through the binder taken to one side of the back thereof and showing the position of the leaf securing portions. 4

' The details of the invention will now be 4more particularly described, reference being had to the drawing in which 5 and 6 indicate-the front and back leaves of the cover of the binderand 7 the connect-ing back interposed between said leaves. 'The back 1s formed with a hollow metallic portion usually made of curved back and front plates 8 and 9 respectively which are crim .edy or otherwise fastened togetherat then' e ges-as l thus formed with alongitudinal recess extending between said plates and portions of i the front plate 9 are cutawayA at 10 to ac commodate and permit the adjustment of the leaf 'securing means employed. The said leaf securing means is made up of slides or l plates .11 which are of approximately the full wldthof the opening in' the back and are arranged to slide longitudinally withiny the space bet-Ween the front andrear plates. The plates 11 are formed with their edges turned over to provide grooves at 12 and 13 1n whlch ring carrying plates 14 and 15 are -movably mounted. The said plates, 14 `and 15 areheld with their meetinn' edges opposite each other, by Amoans of double hea studs 16 the spaces between the heads ofwhich are sufficient to permit the said plates to rock in and out, for opening .and 'closing plates 14 and 15 is such that when they are .the leaf holding means. The width of the brought into the same plane they will tend to force the anges of lthe plate 11 outwardly to some extent sothat in'moving the said plates from one extreme of their movement to theother, they will be sprung by their central positions 'and always tend to occupy oneof said vextremes or the other.

'vThe'said plates 14 and 1.5 carry leaf engaging arms 17 and 18, the ends of which mayA be brought together when the plates 14l and 15 are sprung inwardly as shown in Figs. v1` and 2. 'Themeet-ing ends of the said arms are made to fit upon each other so as to'form a smooth joint andl not to intorferewith the movement ofthe leaves upon therlngs produced by the bringing of said arms together.

For this purpose one of said arms 1s usually providcd'with a V-shaped notch 19 in its free end while the opposing arm is formed with a correspondingly tapered point Q0. llfhenthelcaves are to be putl in' place the arms 17 and 18 are pulled apart as shown in Fig. 3, the plates 14 and l5 being sprun past their central positions in this way an holdingthe said arms 'in open'p'osition; VThe arms 17 and 18, by their engagement, with the` side edges of. the. openin 10, limit-,the

upward movement of the sai vplates 14and 15. After th'e leavesfhave been put in'v .place upon-the arms 17 and 18-theyare snapped togetheragain, vthe parts "assuming the posi-` tion shownll in Fig.` 3. l

' course it will be understood-that Ino'matter how. many rings. are usedthey will be prof ing lelongated openings formed in its front Wall for accommodating leaf `engagilflg` means and adjustable leaf hinging meanshaving flanges forming edge adapted to besprung backI and forth oppoenti points in said openings, and-having lait' securing arms projecting through said vopen- .ings- Q.
